Properties pane for an object gets stuck on Dependencies

[Wolf-SO]

I'm using FlameRobin 0.9.10 with fbclient.dll version 2.1.7.18553 to connect with a Firebird 1.0.3 server. After upgrading from FlameRobin 0.9.2, I didn't check all features, but all I checked worked until I reached the Dependencies.

When I click on Dependencies in the properties window, I get the error message show below and then (after clicking the OK button) the properties view for that object displays Please wait while the data is being loaded... (until closing and reopening this tab):

Seemingly the SQL uses a sub select, this feature requires Firebird version 2+. This moves the lower bound of Firebird versions compatible with FlameRobin to 2.0. This is especially unfortunate because for the client library they state that

The Firebird API is backwardly compatible with the InterBase API.
